The invention relates to elevator installation machinery equipment, in particular to a traction machine installation rack which increases traction force and is high in safety factor. The traction machine installation rack comprises two parallel bearing beams, wherein a support is arranged on the bearing beams, and an installation seat used for installing a traction wheel is arranged on the support; guide wheels are arranged on the support, and a shock absorption mechanism is arranged between the bearing beams and the support; U-shaped rods are respectively arranged at the bottom ends of the two bearing beams, connecting shafts are installed in U-shaped grooves of the U-shaped rods, and the guide wheels are installed on the connecting shafts. According to the traction machine installation rack, the contact length of a traction steel rope and the traction wheel can be increased; under the action of gravity of an elevator car, the higher is the force of friction of the traction steel rope and the traction wheel, the higher is the traction force; the power output by a traction machine can be reduced, and the power can be saved; the higher is the force of friction of the traction steel rope and the traction wheel, the larger is the wrap angle; the traction steel rope cannot be separated from a groove of the traction wheel, the slipping phenomenon cannot occur, and the safety factor is high. The traction machine installation rack has the advantages of being simple in structure, material-saving, and easy to install and repair.
